nvestigation of Morphology of Ti-6Al-7Nb after sulphuric anodizing

Abstract

Titanium alloys possess unique combination of good mechanical properties and excellent corrosion resistance which make them an attractive material for application in many engineering areas. Along with these properties there are some disadvantages which can be eliminated successfully using different surface treatment methods. One of the most commonly used among them is anodizing. This article presents investigation of the results obtained from anodizing titanium alloy Ti-6Al-7Nb using sulphuric acid. The quality assessment and morphology of the anodized layer is made using a micro structural analysis, EDS analysis, XRD analysis and microhardness measurements.
